        This is from memory, which hasn't been too good lately:

        The turn signal switch (new reproductions available) 
        must be installed first.  If you need to replace the 
        switch and have not removed the old one yet, tie a 6' 
        long piece of scrap wire to the end of the wires for the 
        turn signal switch BEFORE you pull the switch out.  
        Tie the other end of the 6' scrap around the lower 
        part of the steering column so you do not loose the 
        end of the wire.  When you pull the old turn signal 
        switch out disconnect the scrap wire, attach it to the 
        new turn signal switch wires and use the scrap wire to 
        pull the new wires down through the steering column.

        The cancel gizmo with the two springs on it has a pin 
        on the underside that fits into a hole in the switch.  
        The screw that the cancel gizmo rotates on has a lock 
        washer that is put on the underside of the cancel gizmo.  
        This size of the lock washer is VERY important to the 
        proper operation of the turn signals.  The screw has a 
        shoulder just after it passes through the cancel gizmo.
        They shoulder tightens the lock washer into a depression 
        in the housing.  If the lock washer is too large in 
        diameter it will not fit into the depression and will 
        cause the turn signals to bind when the screw is 
        tightened.  Same problem occurs if the lock washer is 
        left off or if it is not thick enough when fully 

        The cancel gizmo is activated by the turn signal lever, 
        which screws into the gizmo and has a lock nut to keep 
        it from backing out.  I've never seen a 55.2-56 cancel 
        gizmo, but the 57-59 has the lever coming off at an 
        angle that matches the V of the steering wheel.  My 
        guess is that the 55.2-56 has the lever flat, to match 
        the early steering wheel. 

        The cancel gizmo is cancelled by movement of the 
        steering wheel.  On the backside of the steering wheel 
        you will find a piece that looks like a large washer 
        with a tab on one side.  The tab contacts the cancel 
        gizmo to cancel it.  If there is too much clearance 
        between the steering wheel and the cancel gizmo no 
        contact occurs and your turn signal won't cancel.  
        To change the clearance loosen the screw on the 
        underside of the turn signal switch housing below 
        the hole for the lever.  This screw tightens a wedge 
        that locks the housing in place.  Move the housing 
        to within 1/8" or so of the bottom of the steering 
        wheel and tighten the screw.  If you have the whole 
        mess dis-assembled I would recommend replacing this 
        screw with an Allen head screw.  It makes it MUCH 
        easier to adjust.  If you have a Hydra-Matic (like 
        mine) there is very little clearance between this 
        screw and the collar that holds the top of the shift 
        linkage.  Find the proper sized Allen wrench and cut 
        off the short end for proper clearance.

Hi all,

Does anyone know where I might find info on the reassembly of the column
turnsignal apparatus?  I think I may have it figured out, but I would feel
alot more comfortable if I knew I had all the parts, and in their right
places, before I assemble.

The Chevy Assembly manual and the Chevy Shop manual have absolutely no
reference to it.  I can no longer buy the assembly, so I must restore what I

If you have one, would you mind taking it apart and taking pictures for me?
Just kidding.
